WINDOW-CHAIR.

SPECIFICATION forming part of Letters Patent No. 697,182, dated April 8,1902.

Application filed May 18,1901.

T0 (@ZZ zuhmn it may concern: 7

Be it known that I, JOHN F. STEOKENREITER, 1 of Chicago, in the countyof Cook and State of 3 Illinois, have invented certain new and usefulImprovements in VVindow-Ohairs; and I do hereby declare that'thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the characters ofreference marked thereon, which form a part of this specification.

This invention relates to an improved portable window chair or platformof that class which is adapted to be detachably connected with theframe-sills of a windowin such manner as to safely support a personthereon while washing the window or while doing other work whichrequires a person to pass upon the outside of a window.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of awindoW-chair embodying myinvention and showing also parts of the Window-frame to which it isattached. Fig. 2 is a vertical section on line 1 2 of Fig. 1. Fig. 3 isa detail plan view of the means for detachably connecting thewindow-chair with the windowsill. Fig. dis a section on line 3 4: ofFig. 3. Fig. 5 is an elevation of the looped fixture constituting partof said attaching means. Fig. 6 illustrates a bracket attached to theunder side of the chair and a screw-threaded stud or jack which isemployed for adjusting the chair to the outside sill.

As shown in said drawings, the chair consists principally of a seatboard or platform A, which is hollowed at its center, as indicated at a,to suitably fashion the same for a seat and at the same time to lightenthe chair. Said chair is desirably provided with a rail ing A, extendingaround back of the same and supported partly upon the upper ends ofvertical standards A Said standards are curved at the lower end, asshown, to provide ample space for the clothing of the person using thechair. The chair is supported on the window-frame sill 1 and outsidesill 2 by the following devices:

B B designate two horizontal bars which are attached to the under sideof said chair by means of bolts or the like and are detach- Serial No.60,822. (No model.)

ably connected at their forward ends to parts connected with thewindow-sill 1. Desirably said bars are set into downwardly-openinggrooves in the chair, so as to be flush with the bottom of said chair.Said bars are desirably extended across the principal part of the widthof the chair, so as to thereby strengthen the seat or platform andprevent the same from warping.

G designates a bracket attached to and depending. from the lower side ofthe chair and provided with arms 0 c, by which said bracket is connectedwith the chair, screws or like fastening devices being for this purposeemployed. Said bracket is provided between its ends with a substantiallyvertical opening which receives a screw-threaded stud or jack D, whichpasses upwardly through said opening and is supported at its lower endon the outside sill of the window-frame. Said stud D is provided at itslower end with a flange or head (1 to afiord an ample bearing therefor,and desirably the lower end of said head is faced with a disk D, ofsuitable yielding material-such as leather, rubber, or the like-thepurpose of said yielding disk being to prevent defacement of the outsidesill and to enable the parts to adjust themselves to sills of varyingpitches.

The means for detachably connecting the forward ends of the bars 13 withthe-windowsill are made as follows:

E E designate metal loops which are provided with flanged bases E, whichlatter are apertured to receive screws by which the loops are fastenedto the window-sill. Said loops E may be made of any desired shape, andthe cross-sectional form of the supportingbars B will be made tocorrespond with the shape of the loops. The flanged bases E of saidloops are inclined to correspondwith the general inclination or pitch ofthe window-sill, as clearly shownin Figs. 2 and 4, so that when the loopis attached to the sill the loop proper will assume a generally verticalposition thereon. The extremities of said supporting bars 13 areprovided with upturned or hooked portions B, which pass through theloops E, and when said bars assume a horizontal position, as shown inFig.- 4, the hooked end portions of the bars ongage the loops in suchmanner as to prevent the bars and the chair connected therewith beingmoved outwardly so long as said chair and bars remain in a horizontalposition. Said bars are provided inside said hooked end portions withinwardly-facing shoulders Z), which are adapted to engage the outerfaces of said loops when the bars are in their horizontal positions,thereby preventing the bars movinginwardly. For this purpose said barsin their principal parts are made of greater width than the loops E, andthe extremities thereof, which pass through the loops, are reduced inwidth, thereby forming the inwardly-facing shoulders I). With thisconstruction it will be seen that when the bars and chair assume ahorizontal position said bars are locked from longitudinal movement byengagement of the upturned or hooked end portions B with the inner facesof the loops and of the shoulders I) with the outer faces thereof.

When the window-chair is to be placed in position, said chair and thebars 13 are made to assume a substantially vertical position, whichpermits the hooked ends of the bars B to pass into and through the loopsF. When said hooked ends of the bars have been inserted into the loops,the chair is swung downwardly, the loops E acting as a hingefor thismovement, until the chair is brought to a substantially horizontalposition, the contact of the jack or stud D with the outside silllimiting the downward movement ofthe chair. When the chair has beenbrought to a horizontal position with the jack or stud D resting on theoutside sill in the manner shown in Fig. 2, said parts are lockedsecurely to the outside and window sills and cannot be detachedtherefrom until the chair is swung upwardly into a substantiallyvertical position. When the chair is to be detached from thewindow-frame, it is swung upwardly to an approximately verticalposition, when a slight outward movement is suflicient to release thehooked ends of the bars B from the loops. The parts of the bars whichengage said loops are made of slightly-less vertical thickness than thewidth of the loops, as shown in Fig. .4, thereby permitting the chair tobe adjusted (to varying pitches of the outside sill by verticaladjustment of the stud or jack D. The stud D is threaded, so as to turnfreely in the bracket 0, thereby enabling this part of the device to beadjusted by hand, and in order to secure the necessary strength to thispart the threaded aperture in the bracket 0 is made somewhat longer thanwill ordinarily be required for a given-sized stud. The attaching-loopsE are located opposite the parting-strip 3 of the Window-frame, so thatsaid loops do not interfere with the free movement or closing of thewindow-sashes. The

stud orjack D is adapted to be supported on the outside sill near theouter margin thereof, so as to enable the seat to be made large enoughto give sufficient room outside of the window to permit a person usingthe same to have all the space required for washing the Window or fordoing other work required.

' The mechanism herein shown may be advantageously employed in awindow-platform construction made the full width of the window, and inthis instance two or more jacks or studs D may be employed and more thantwo bars B may be used:

The device shown is extremely simple in its construction and may be madeof ample strength andat the same time sufficientlylight to enable thesame to be handled by persons accustomed to washing windows and do likework about a house.' Moreover, the attaching means shown are such as toeffectually prevent displacement of the chair when in its operativeposition, and thereby reduces to a minimum danger of accidents arisingfrom the imperfect operation of the interlocking parts.

I claim as my invention- 1. A window-chair comprising a solid horizontalseat or platform, bars attached to the lower side of said seat andextending from front to rear thereof for the purpose of reinforcing saidseat, the extremities of which bars extend forwardly beyond the seat andare adapted to be detachably connected with fixtures on thewindow-frame, brackets detachably secured to the under side of the seat,one at 62.011 side thereof, each of said brackets being provided witharms by which it is attached to said seat and with a part having avertical screw-threaded opening, and a screw-threaded stud or jackextending upwardly into said opening and provided at its lower end witha head or flange which is adapted to be supported on the outside sill ofthe window-frame, said studs or jacks be ing located entirely below theseat and vertically adjustable in said brackets from below the seat.
